The ACM Turing Centenary Celebration took place in San Francisco on June 15-16. It brought together 33 winners of the ACM Turing Award and other influential members of the computing community in a two-day event was webcast and is now available to view as a set of videos.

The first webcast opens with a short photo-documentary outlining Alan Turing's career, then after welcoming remarks from ACM CEO White and an introduction to the event from Vint Cerf, there's first panel discussion, Turing the Man. In this session we hear from three people who met Turing personally, including William Newman, the son of Turing's friend and mentor Max Newman.

Talks that interspersed the panel sessions have also been videoed, including Alan Kay's with the intriguing title Extracting Energy from the Turing Tarpit! and Dana Scott's Lambda Calculus Then and Now.

The program for the event is available online together with some twelve hours of video.
